Is there one particular reason why Selena Gomez won’t return any of Justin Bieber’s phone calls? It seems the “Beauty and A Beat” singer has reached out to her former girlfriend several times lately but received no response.

According to a report from Hollywood Life, it seems Selena has had more than enough. She even thinks Justin’s recent behavior has gone way beyond immature and all the way to weird.

“Justin calls Selena from time to time, but she’s over him. Selena has kept an eye on Justin in the news and just laughed and laughed. She doesn’t give a s**t anymore. Justin is crazy and she doesn’t want to be his mom anymore. She feels so free and loves hanging out with her girlfriends. He’s weird and she doesn’t find his behavior hot or anything. She just wants a man who has his s**t together, and not a weird boy,” a source close to the Spring Breakers star says.

Justin Bieber has had a rough couple of weeks, replete with wearing an oxygen mask while shopping in London, swearing at and practically assaulting a member of the paparazzi and finally–passing out on stage and going to the hospital.

Selena Gomez is likely afraid that if she takes even one of Justin’s calls he will misconstrue it for a sign of reconciliation, and it certainly doesn’t sound like that’s even a remote consideration.

Do you think Selena is doing the right thing by avoiding Justin Bieber’s calls? At least she isn’t leading him on or fueling him with false hope.
